Automatic control multi-stage biomass burning system

Abstract

The invention discloses an automatic control multi-stage biomass burning system. From the first burning chamber, a smoke exhaust drum of a front burning chamber is communicated with a hearth of a rear burning chamber, and the smoke exhaust drum of the last burning chamber is used for exhausting smoke. All the smoke exhaust drums are provided with a temperature sensor. Air inlet pipes of the burning chambers are all provided with an air inlet adjusting valve. A signal receiving end of a controller is connected with the temperature sensors on the smoke exhaust drums of all burners. A signal output end of the controller is correspondingly connected with feeding devices of the burners and the air inlet adjusting valves in a one-to-one mode. Burning conditions of biomass fuel are known by measuring smoke temperature, the feeding devices and the air inlet adjusting valves are controlled through the controller, the feed amount and the air inlet amount are changed and automatically controlled, operation difficulty and operation cost are reduced.

Description

technical field [0001] The invention relates to the technical field of biomass boiler equipment, in particular to an automatic control multi-stage biomass combustion system. Background technique [0002] With the increasingly severe environmental pollution and the depletion of existing mineral energy, adjusting the energy structure and using a large number of clean and environmentally friendly energy instead of heavily polluting coal, oil, natural gas and other fuels have become the focus of attention of all countries in the world. Among the clean and environmentally friendly energy sources, biomass fuel has become a new favorite in this field due to its low price, clean and environmentally friendly advantages. The use of biomass fuel can not only effectively use natural resources, but also reduce greenhouse gas emissions and protect our living environment. . Therefore, countries all over the world are vigorously researching and developing biomass combustion technology. ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the control of the biomass combustion system is generally manual or semi-manual, that is, in the process of use, it is necessary to frequently observe the combustion situation of the biomass fuel, and manually adjust the amount of feed and air intake according to the combustion situation, which is very important for the operation. The experience requirements of personnel are relatively high, and the operation is cumbersome and the operating cost is high
